航空电源航空科技重点实验室学术年会 (APSC’ 20 12)论文集 电动汽车无线充电技术的研究进展 曹玲玲 陈乾宏 阮新波 （南京航空航天大学航空电源航空科技重点实验室 南京 210016） Review of the wireless power transmission technique for electric vehicles CAO Lingling CHEN Qianhong RUAN Xinbo (Nanjing University of Aeronautics Astronautics, Nanjing 210016, China) Abstract: Wireless Power Transmission (WPT) technique will 发展电动汽车，是世界公认的缓解能源短缺和环境 become the development trend of energy supply system for 污染的有效策略，而对于我国又显得至关重要。以我国 electric vehicles (EV), which features the advantages of energy 的石油消耗为例，2009 年石油净进口量约 2.04 亿吨， saving, low pollution and low-carbon emission. It is pointed out 进口依存度达 52%，远超过国际警戒线标准 35% 。其中 that electromagnetic induction and electromagnetic resonance of 车用燃油消耗占总石油消耗的 1/3 强。因此，开发、推 the three commonly used WPT techniques are more suitable for 广汽车代用燃料和电动汽车，降低燃料消耗，对缓解我 EV charging owing to their higher efficiency. With the purpose of 国环境污染、保障能源安全和供给以及国家的可持续发 efficient energy transfer for EV power system, a review on the 展具有重要的战略意义[1]。因实现了零排放、技术相对 topology, control and transformer of current-used WPT technique is made. It is indicated that contactless transformer is the major 成熟、经济性较好，由蓄电池供电的纯电动汽车(Electric bottleneck restricting the system’s efficiency, and further, the Vehicle, EV)成为各国政府鼓励、各汽车生产商大力发展的 for a more efficient transformer are discussed. As for 环保车型[2]。受动力电池容量的限制，目前EV 的续驶里 electromagnetic induction WPT, the problems of “low coupling 程较短，电池充电站的建设成为制约EV 应用、发展的最 coefficient” of the contactless transformer and “uneven 大瓶颈[3,4]。为此，各国均大力进行充电站建设来推动 EV distribution of magnetic flux” in mobile charging s
